====== Message List ======

This module (''msglist.js'') can be used as a full-screen scrolling user interface for listing messages (public posts and private email messages) and reading and replying to messages.

{{:module:msglist_screenshot.png?600|}}

This module was first demonstrated in this [[https://www.youtube.com/watch?v=5mwimlWJOko|video]].

===== Dependencies =====

For full/proper function of this module, you'll need a recent v3.17c dev-build (as of March, 2020) of Synchronet, or later.

This module may require an update of your Synchronet ''exec/[[dir:load]]'' directory to get the latest ''.js'' load-libraries, including the newly added ''age.js''.

The following menu files are used by this module:
  * ''[[dir:text]]/menu/msglist.asc''
  * ''[[dir:text]]/menu/msgview.asc''

===== Install =====

==== System Modules ====

Run ''[[util:jsexec]] msglist.js -install''.

This procedure this will configure the "Read Mail" and "List Msgs" modules in [[util:SCFG]]->System->Loadable Modules with command-lines that call this module to handle those system functions from all built-in menus and stock command shells.

==== Menu Command ====

If you wish to allow your BBS users to list sub-board messages directly from a Baja command shell menu (e.g. using the 'L' command key from the main or message menu) add the following command key handler to the desired command shell source (''.src'') file(s):

for Synchronet v3.18 or later:

<code>
cmdkey L
    msg_list
    end_cmd

</code>

for Synchronet v3.17 or older:

<code>
cmdkey L
   exec_bin "msglist"
   end_cmd
</code>

... and then recompile the source file with [[util:baja]] (e.g. ''baja default.src'').

In Synchronet v3.20, the default command shell (''default.js'') already has main menu ''L'' command key mapped to the BBS message list function.

===== Configure =====

The behavior of this module is sysop-configurable through the use of command-line arguments and the ''[[config:modopts.ini]]'' file.

==== Command-Line Options ====

^ Option        ^ Description ^
| ''-preview''  | Enable the message preview pane by default |
| ''-nospam''   | Don't load SPAM-tagged messages |
| ''-spam''     | Only load SPAM-tagged messages |
| ''-unread''   | Only load unread messages |
| ''-reverse''  | Reverse the default message list order |

==== modopts.ini ====

The ''[msglist]'' section of the ''[[config:modopts.ini]]'' file may be created by the sysop to customize the look-and-feel of this module.

If a ''[msglist:<code>]'' section exists, then those settings will take precedence when the module is being used to list/view messages in the message base with the specified internal //code// (e.g. ''[msglist:mail]'' for the mail message base).
